China ZD Cylindrical Gear Speed Reducer - Suppliers and Factory for Various Industries
⚙️ Product Application Scope
1
The high-speed axle rotation shall not exceed 1,500 revolutions per minute.
2
The circumferential speed of gear transmission shall not exceed 20 meters per second.
3
The working environment temperature is -40°C to 45°C. If it is below 0°C, the lubricating oil should be preheated to above 0°C before starting. The gear reducer can be used for both forward and reverse operation.
✅ Conditions of Use
🔧 Maintenance
1
Regularly Check the Oil Level
Check the oil level once a month or every 500 hours of operation to ensure it remains within the specified range.
2
Regularly Change the Lubricating Oil
- First oil change: Perform the initial oil change 36 hours after first operation to remove metal particles generated during the running-in period.
- Subsequent oil changes: Replace lubricating oil every 2,000–5,000 hours of operation or every 6–12 months, depending on working conditions. Shorten the interval under harsh conditions (high temperatures, excessive dust, or continuous heavy loads).
- Oil change method: While the reducer is still warm (oil maintains good fluidity), drain the old oil and refill with new oil to the specified level.
3
Keep Clean & Ensure Vent Cap is Unobstructed
Regularly clean oil stains and dust from the reducer's surface. Inspect and clean the vent cap to prevent clogging.
4
Fastening Inspection
Regularly check whether all mounting bolts and connections are loose.
⚠️
Handling Abnormal Situations
If a sudden increase in noise, intensified vibration, abnormal temperature rise, or severe oil leakage is detected — stop the machine immediately for inspection. Operation may resume only after the issue has been resolved.

❓ Frequently Asked Questions (FAQ)
Q What is the maximum input speed for this gear reducer?
The high-speed axle rotation for this gear reducer shall not exceed 1,500 revolutions per minute (RPM). Exceeding this limit may result in reduced performance or equipment damage.
Q Can the gear reducer operate in extremely cold environments?
Yes. The reducer is designed for working environment temperatures between -40°C and 45°C. However, if the ambient temperature is below 0°C, the lubricating oil must be preheated to above 0°C before starting the machine to ensure proper lubrication.
Q How often should I change the lubricating oil?
The first oil change should be performed 36 hours after initial operation. Subsequent oil changes should be carried out every 2,000–5,000 hours of operation or every 6–12 months. Under harsh conditions (high temperature, heavy dust, or continuous heavy loads), the interval should be shortened accordingly.
Q What is the transmission efficiency of this gear reducer?
This gear reducer offers high transmission efficiency: single-stage greater than 96.5%, two-stage greater than 93%, and three-stage greater than 90%, making it highly efficient for industrial applications.
Q What should I do if I notice unusual noise or vibration during operation?
If you detect a sudden increase in noise, intensified vibration, abnormal temperature rise, or severe oil leakage, stop the machine immediately and perform a thorough inspection. Do not resume operation until the root cause has been identified and fully resolved.
Q What material are the gears made from, and how are they processed?
The gears are manufactured from high-strength low-carbon alloy steel using a carburizing and quenching process, achieving a tooth surface hardness of HRC 58–62. All gears are precision-machined using CNC grinding technology to ensure high accuracy and excellent contact performance.
